CAR-=COUPLHNG.

SPECIFICATION forming part of Letters Patent No. 690,954, dated January14, 1902.

Application filed June 4, 1900. Renewed June 10, 1901. Serial No.64,027. (No model.

' HOLMES, a subject of the Queen of Great Britaim and Ireland, and aresident of Liverpool,

England, (whose post-office address is 312 Kensington, Liverpool,England,) have invented a certain new and useful Wagon-Coupling, (forwhich I have applied for patents in Great Britain, No. 5,782, datedMarch 28, 1900, and No. 8,539, dated May 9, 1900,) of which thefollowing is a specification.

This invention relates to railway-vehicle couplings which are partiallyautomatic in their action.

Reference being had to the drawings, Figure 1 isa side view, and Fig. 2is a plan, of a coupling arranged according to myinvention. Figs. 3, 4t,5, and 6 are detail views showing parts of the mechanism separately.Fig; 7 is a side View, and Fig. 8 is a plan, of a modified form of myinvention.

The coupling (1 (shown in Figs. 1 and 2) is of the ordinary three-linktype. Pivoted to a spindle 12, disposed across the wagon end andprovided with operating-levers, is a liftingarm 0. This arm is shownmore clearly in Figs. 3 and at and comprises two portionsnamely, thecradle 01, which supports the outer link of the coupling, and thetubular portion 0, into which such cradle telescopes when it comes incontact with any obstruction. The cradle d has a specially-formed jaw e,adapted to receive the outer link, and is extended by the springs f inthe tubular part c. The lifter c is pivoted at g to the spindle 5,whereby it may move to right or left, and so place the coupling on thehook of the next wagon, even when the two wagons are standing on acurved track, and this right or left movement is effected by the drawrodh, which is shown more clearly in Fig. 5. Projecting from the rod 7t isa plate 1', which engages a pin j on the lifter c. A handle is formed oneach end of the rod h, whereby it may be pulled, and so the lifter andcoupling are rocked to one side or the other. The rod 7t isbcarried inguides attached to the spindle Keyed on the spindle bis a gapped diskIt. (Shown separately in Fig. 6.) This disk is engaged by aspring-actuated detent Z, which retains the coupling in the raisedposition assumed in Fig. 1namely, in position for engagement with thehook of the next wagon. This detent is withdrawn from engagement withthe disk 70 automatically on impact of the two wagons by means of theinclined plane in on the rod n, the bell-crank levers 0, and the barswhich latter are disposed in rear of the buffers q. The return action ofthese parts is due to the spring '2'.

The rod n is provided with handles, whereby the detent may be withdrawnby hand. The disk 71, possesses two gaps, one being engaged by thedetent l when in the raised position above referred to, the other gapbeing engaged when the litter c is lowered and out of use.

In Figs. 7 and 8 a two-part shackle-coupling is shown operated by alifting-arm 0, projecting from a spindle b, on which is keyed the gappeddisk 76. The disk 76 is engaged by the detent Z and is released in themanner described with reference to Figs. 1 and 2.

Having now described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. In combination, the lifter c pivoted to its operating-spindle b, thegapped disk on the spindle Z), and the detent Z engaging such disk andarranged to be withdrawn from such engagement by the inclined plane 172,rod 'n, levers o, and bars 19 on impact of the buffers q, as described.

2. The combination with the lifter-operating -spindle b, of the gappeddisk 70 keyed thereon and engaged by the detent Z, and means such as theinclined plane on and rod 01 for withdrawing such detent and releasingthe lifter, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
